The Barter Club was the revelation. I have learnt from experience to be skeptical and quite hard nosed when told that someone has set up a totally new economic system that is drawing in millions of impoverished Argentines. Surely the men behind it must be ripping them off; surely they must be after political power. But no. The founder, Ruben Rivera, may talk too much but he is quite simply trying to find solutions for the millions failed by Argentine politicians. Do I believe it will work in the long run? That is irrelevant: the privilege and delight of filmmaking is to meet such people and to tell their stories.
